About Chase Cryogenics

In 1993 Dr. Simon T. Chase started a small business enterprise, based in Sheffield and trading as 'Chase Research', to design and produce simple and reliable sub-Kelvin cryogenic coolers for the research market. Chase Research became incorporated as Chase Research Cryogenics Ltd. in January 2003, and is continuing to expand and develop new and improved cryogenic cooler types.

 

Our main activity continues to be the design and production of sub-Kelvin cryogenic coolers, mainly for research applications, and with a strong emphasis on custom design to individual specifications. Historically, most of our customers have come from the astronomical research community, and our evaporation coolers (sorbtion coolers) have cooled the detector arrays of many groundbreaking experiments of the last decade.

Chase Research Cryogenics Ltd. design and manufacture a wide range of 'plug and play' sub-Kelvin coolers, with applications in astronomy, molecular spectroscopy and materials science.

 

Main product lines:

 

- Closed cycle 3He evaporation coolers, designed to operate from either wet (Liquid ⁴He) cryostats or mechanical coolers (e.g. Pulse Tube coolers). Configurations developed at Chase Research Cryogenics include single stage ('He-3' type), two stage ('He-6' and 'He-7' types) and triple-stage ('He-10' types) typically running at temperatures in the range 350 to 220mK, and with run times per cycle ranging from 24 hours to one week. Features include low turnaround times, very simple operation and easy interfacing. Cooldown from room temperature to liquid Helium temperature (4.2K) will typically take less than 24 hours, and cycling from 4K to the operating temperature typically takes between one and two hours, depending upon the configuration and application.

 

- Gas-gap heat switches of many different designs and specifications.

- Calibrated diode thermometry for applications down to around 1 Kelvin.

- Other speciality products designed to customer specifications.

- UNDER DEVELOPMENT: Small self-contained ³He/⁴He dilution refrigerators to reach operating temperatures in the range below 100mK.
